A big hello to all mankind! Visit my youtube channel to 
and find various interesting things on Electrical ~ Mechanical and Electronic ~ Technology...
 
Buying one helps my research tremendously,
 helping me get all the supplies I need for the future.
Joule Thief
After many years of experimentation on the circuit 
of Joule Thief with Toroidal Transformer,
I decided to make with great love the best Joule Thief i have ever made so far. 
Believe Me you will not find anywhere in the market something like this. 
 
That alone makes it unique.
 
The big challenge was to cover two different batteries in one circuit and 
to be able to see the values for each one through a multi-function counter.
This way you will know at any time what condition your battery is in, 
and how long it has been running.
 
The most efficient, in terms of consumption and lighting with absolute control 
and a large range of measurements will become the 
ultimate Emergency Light. 
 
Utilize AA batteries that are old and steal 
all the last energy from them...
 
At the same time 3,7volt Reachable ones.
 
Dual function device and with the ability to see 
the measurements separately from each battery.
 
With toggle switch to working in HIGH and LOW operation.
 
Dimmable & Rechargeable
 
 
How to operate it!
 
There are 4 switches, one "big black" is for the operation of parameter tester 
to see the battery voltage / current / watts for each battery. 
There is also a smaller black one that data set the parameter tester in time of Ah.
The main switch is to operation the device and select one of the two batteries 3.7v & 1.5v.
The small switch is to select LOW or HIGH mode.
 
The yellow knob is a potentiometer to increase the intensity of the Bulb!  
The "orange pcb terminal" is also an "input power" for the charger module to charge the battery.
You can use any DC power like is a "solar panel" with characteristics of 5 volts / 1A.
 
You can use "dimmable" and "low curent" consumption Ε14 led lamps 
1.5watt to 5watt, AC 120v or 220v.
 
If the device "does not work", you will need to charge it.
 
You do not have to put out the battery and put them in a wrong "polarity" way.
This will "destroy" the battery charging board! There is no reason to remove the battery.
 
Τhe battery are have big "capacity", So if the battery are discharged "empty",
you will have to wait for "some time" until it recharges.
 
It is rechargeable and charging with micro usb. 
 
First charge over 10 hours. This way the battery will be fully activated
 
When the "RED led" lights up on charger module means it charges the battery.
When the "BLUE led" lights up on means that the battery is charged.
 
 
 
 
 
 
NOTE
 
Maybe there are small differences in electronic components 
and materials (like bigger batteries etc) 
due to device enhancement for the buyer's benefit!
